Markiewicz, PhD,‡ and Ajay Bansal, MD†§  \nAbstract: Colorectal cancer (CRC) continues to be a signiﬁcant public health problem worldwide. CRC screening programs have reduced the incidence rates of CRCs but still suffer from the problems of missed lesions and interval cancers. Chemopreventive strategies against CRC would beneﬁt high-risk populations but trials testing synthetic and naturally occurring compounds have not yielded a front runner. Immune mechanisms promoting cancer have been modulated to develop immunotherapy for cancer treatment that has revolutionized cancer management, but could also be applied to cancer interception, that is, cancer immunoprevention. Cancer immunoprevention refers to approaches that can enhance the immune system, either directly or by removing natural breaks such as immune checkpoints, to survey and destroy tumor cells. In this primer, we aim to explain the concepts behind vaccine-based cancer immunoprevention. Multiple cancer vaccines have been tried in advanced cancer populations, but most have failed primarily because of an immunosuppressive environment that accompanies advanced cancers. Preventive vaccines in immunocompetent hosts may have a better clinical response compared with therapeutic vaccines in immunosuppressed hosts. The ﬁrst randomized controlled trial testing the mucin1 vaccine against CRC in the prevention setting has been successfully completed. For the beneﬁtof the clinician, we brieﬂy discuss important concepts related to the workings of preventive vaccines. Prevention with vaccines is a highly attractive approach because of the potential for highly targeted therapy with minimal side effects that could theoretically provide lifelong protection.  \nKey Words: cancer immunoprevention, vaccines, colorectal cancers (J Clin Gastroenterol 2023;57:246–252)  \nColorectal cancer (CRC) is the third most common  \ncancer globally, representing 10% of cancer diagnosesand 9 .4% of cancer deaths worldwide.1 Because of its public  \nFrom the *Department of Medicine, The University of Kansas Health System; †Division of Gastroenterology and Hepatology; ‡Department of Microbiology, Molecular Genetics and Immunology, The University of Kansas Medical Center; and §The University of Kansas Cancer Center, Kansas City, KS.  \nThis work was supported in part by the NIH/NCI Cancer Center Support Grant P30 CA168524 to AB.  \nM.A.M. is a paid consultant for Design-Zyme, LLC.
